T 0 all @t1/0m it may concern:

yBe it known that I, KARL Wnssiiii, ai citizen of the United States,rcsiding at St. Paul, in the county` of Ramsey and State of Minnesota, have` invented Icertain new and useful improvements in Machines for Making ce-Cream Cones; and I do hereby declare the following to be a' full, clear, and exactY description `of :the invention, sucli'as will enable others skilled it apper'tains to make and use the same.

My Vpresent invention has for its` object to provide fa `machine of'liigli, capacity for making baked cones or cornets such'. as are:

extensively used for holding ice cream.

rTo the above ends the invention consists of the novel devices andzcombinations of de.-

viccs hereinafter described and defined in` the claims. 1

. In this improved machine l employ' a very large number of molds which are preferably made conical and connected in series to carrying bars, which bars are arranged in an endless series, to `forman endless metallic belt of considerable width.

-Suitable guiding means AIor lthe mold- 'equipped' bars, and 'means for imparting traveling motion to theendless sei-lesbi" belt thereof, are also provided.4 F or coperation with these mold-equipped bars, I provide several series oilcores, 'e1-ably of conicall form,

prefloose individual hars. The number of core-- equipped bars may be very much less than the number of mold-equipped bars in the endlessl belt, but the number of cores on each bai' should be equal to the number of molds oneach bar of the said belt;

By means of :i sti-called bar shifter, prefeiablv afforded by vided with core bar holders, the core equipped .hars :ii-c .iii succession, positioned in thev alined molds of the" endless belt; bv said core bar shifter, thecore bars are, in succession, picked out of the molds, after they vhave traveleda proper 4distance therewith and have remained therein/for a sulii# cient interval of time to permit hakingof the dough which 'is injected into the moldsb just before the cores are inserted preferably therein'. f

Suitable means is also provided for accurately positioning the cores of the molds in the art to which 1 and connected to a pair of Wheels pro-nand land ioi holding the same thuspositioned While traveling with the molds.

in the i accomp anying drawings which illustrate the improved machine, like characters indicate lil several views.`

Referring plan view of the parts beingg shown te parts throughout the f i to the drawings, Figurel is a improved machine, some in section and sine parts being'broken away. Fig. Qis a side'elevation oi the said machine. -Fig. 3 is a veiv tical `section taken on the line m3 of F ig.

link 10 connects the free ends of the arms 8,

vand this' link, as s hewn, is provided with a,

belt, dependingl are vclosely connected neartheir ends, .by hinged joints 6. The ends of Work in endless groovesshaft 15 journaled in end, with a small spur gear 18 which, in

turn, meshes with'a spur pinion 19 carried by thehub of a pulley'20,lwhich pulley 20 and an idle'pulley 21 are `journaled on .a shaft'22 rigidly secured to the sides. of the -frame 1. The chainv of driving gears and the pawl and ratchet devices above described' serve to transmit, from a pulley running at Y. step movement to the of the mold-equipped .bars

Extending transversely and centrally of distance vabove'the upper portionof thevendle'ss belt made up of the said mold-equipped. bars, andl journaled in suitable bearings afforded by the side plates of the frame 1, is a shaft 23that carri'esa pair of large laterally spaced gears 24 which, as shown, mesh with pnions 25 carried bythe counter shaft 15. yThe shaft 23 4is' journaled in'bearings 26, supported on the intermediate portions of horizontally extended guide as-shown, are

bars 27. These' guide bars 27, supported from the sides of the frame ,1Y by angle'brackets 28, and the said bars extend parallel to but are spaced apart .from the horizonte1 upper edges of as to afford guide channels 29,- for an important purposewhich will presently appear. On their inner faces arighted core .bar

and will carry the same upward, forward, fand deposit the same againinan operative position, as before stated, atr the receiving end of the guide Thiis'it will be seen that cores move-.in endless circuits or orbits which are located entirely outside of each other, such cirpuits being sup,erposed,'ifan the two endless series moving ingo osite directions. These series of devices yw ich in reality forni coperating mold: sections,have their runs substantially coincident with each other -throughout a vcertain distance, that is "to say, the upper run of the lower series sub.-

stantially coincides with the lower run of the upper series, the moldsl and coresbeing coincident portion of the rlihs-while'ftheby' means of the heating device over which the mold sections move.

Just'` before the. molds, as amount of dpugh, `iiu'id condition, .wi-ll be. inserted intol the rmme from a suitable pumping 0r injecting device; and a'svthe' molds having cores therein are moved together they will be subjected above described, the proper in light' plastic or semi-- the molds and the cores are inserted iso l tion of each discharge conduit 39 is a pump plunger or ejector 40, all of Awhich I 8, link 1Q, crank rod l2, land crank or eccentric 13 areduplicated. on opposite sides of ,meente Atoa bakingA heat .rorn-a'suitable burner located .within a sort of an oven formed within the endless belt inadeup of the mold bars 5 and between the sides of the frame l.; The dough supplying device comprises a .trough 38 which has a multiplicity of dis-r charge conduits 39 so disposed transversely of the 'machine that one will always be vertically alined with onek of the molds Al of a.A

mold bar positioned below the same l Working in the vertically-extended porp'lungers are secured at their upper `ends to a transverse bar 4l. `Art ts ends the har 4l .is pivotally connected to the upper ends of .a pair oftransversely spaced upright links 42, the lower ends of which latter 'are pivuotally'connected to arms 43, shown asy cast integral withv the arms 8 before described;I

and it should be here stated vthat said, arms the machine for the purpose of. imparting parallel upward and downward movements to the ends of the bar 4l. 'It should also be here, noted that the pump Aplungers 40 will -bemoved downward while the' driving pawls 11 Aare making their return or 'idle movements on they ratchet wheels 9, and thatV ysaidratchet wheels, and hence the molds 4,'

are given their intermittent movement by said pawls 1l while the pump plungers 40 are making their return or upward movements. Thus it will be seen that the dough yis inserted into the underlying molds while the 'latter are stationary.

The gas burning device, as shown, is in the form of a pipe 44; which has a multiplicity .of transversely extended twyerrpipes 45 properly positioned to direct the flame upon the mold in which the cores and.

` dough are inserted. By reference to Fig. 3

it" will Vloe noted that one of the side plates 1 'of the frame is cut away, at 46, to permit the required air toenter the oven. It will, of course, be understood that the amount of [dough dropped into each mold should be such that when the core` is inserted therein,

' -mold e By the time the cones or cornets have thedough will just rise to the top oi the passed from the rear o r right hand extremi ties, viewed in Fig. 3, of the guide channels 29, they will he properly baked; and after the'cores have been removed they may themselves be 'removed from the molds, by hand or by any other suitable means. In

Fig. '8 these baked cones or cornet-s are indicated in section by the character y.

Y As abovedescribed and as illustrated in the drawings, the mold-equipped bars 5 are connected by hinges, but in some instances it may be found preferable simply to use disconnected` cone-equipped 1n close Contact, arranged to slide in the" endless guide channels or on guides ofother suitableform. f

This invention is believed to be a pioneer in the art of making cones or receptacles-vof.

the character indicatedand it will, therefore, be understood that the broad claim's'of this application are not limited to the spe` lAciiic construction shown inthe drawings:

Attention is called to the fact that in Fig.`

2 the teeth of the gears 24 are shown only part way around the same, while as a matter of fact they will extend Jcompletely y around thesame, as indicated by broken llines. Attention is also called to the' fact that in Fig.y 3 the gears 24 are indicated `only by dotted lines.-

Asa possible modification of this ma-y up sectional molds, which may take various .forms accordingto the shape or character -of the article that is to be baked, andhence, that the broad claims of this Vapplication are not limited .to theform or internal shape of such molds.
